根据在包头和沈阳有关稀土推广应用会议的安排,鞍钢与包钢冶金所、沈阳金属所等组成16MnRE冶炼工艺和加入方法专题攻关组,研究16MnRE钢的稀土加入方法,寻找防止水口结瘤和汤道堵塞的途径。1976年11月进行了第一次试验,着重从操作工艺和一般质量检验方面考察在钢锭模内吊挂混合稀土金属棒的方法。这种加入稀土的方法是解决加稀土钢浇注问题的途径之一,对它进行深入的研究,对巩固和扩大稀土在钢中的
According to the arrangements for the promotion and application of rare earth in Baotou and Shenyang, Anshan Steel and Baotou Steel Metallurgical Institute, Shenyang Metals and other 16MnRE smelting process and join the special research group to study the rare earth join 16MnRE steel to find ways to prevent nozzle nodules and soup Road blockage approach. The first test was carried out in November 1976, focusing on the method of hanging mixed rare earth metal rods in ingot molds from the aspects of operation technique and general quality inspection. This method of adding rare earth is to solve the problem of adding rare earth steel casting one of the ways to carry out in-depth research on the consolidation and expansion of rare earth in steel
